Thanks, applied to my net-next tree for QEMU 1.8: https://github.com/stefanha/qemu/commits/net-next Will you be around to maintain and test this in the future? Please add yourself to the ./MAINTAINERS file for net/netmap.c and submit a patch. It's important we have someone who can keep this code working over time. Otherwise the feature may get dropped again due to bitrot. Stefan
